Use proper lifting and carrying techniques whenunpacking and moving the components.• Make sure each FS7500 Controller is fully grounded at all times to prevent damage from electrostaticdischarge.• When handling an FS7500 Controller, use the electrostatic wrist guard shipped with the controller or asimilar form of protection. See Hardware Protection on page 4.• Hold the hardware level with the rack when you install it.Warning: The BPS contains LETHAL VOLTAGES. All repairs and service should be performed byAUTHORIZED SERVICE PERSONNEL ONLY. There are no customer replaceable parts insidethe BPS.• Unpacking the BPS in a low-temperature environment might cause condensation to occur in and on thechassis. This could cause electric shock.

Make sure touse power cables rated for the correct input power source rating. The rating is on a label next to the inputconnector on the power module rear panel.Hardware ProtectionWhen not installed in a rack, an FS7500 Controller must be in its original packaging or placed on a sturdysurface that is protected from electrostatic discharge.When handling an FS7500 Controller, make sure you use the electrostatic wrist strap that is shipped with thecontroller or a similar form of protection.Using an Electrostatic Wrist StrapYou must protect sensitive hardware from electrostatic discharge.To use an electrostatic wrist strap:1. Connect the steel snap on the coil cord to the stud on the elastic band. See Figure 2.4EqualLogic FS7500 Installation and Setup 1 Before You Begin
